The National Highways Authority of India (NHAI) serves as the primary agency under the Ministry of Road Transport and Highways, which is responsible for the development and maintenance of National Highways. These highways are the backbone of India’s road network, ensuring seamless connectivity between cities, towns, and villages. They play a source of transportation of people and goods, which is essential for economic growth. National Highways contribute to national security by supporting military logistics and strategic mobility across the country.
National Highway
National highways are approximately 2.7% of India’s total road network and play an important role in facilitating the movement of people and goods across the country. The establishment of the National Highways Authority of India (NHAI) Act laid the foundation for the development and management of these highways. India has one of the most extensive road networks globally, ranking as the second-largest in the world. Some of the major National Highways in India include NH 65, NH 147, NH 41, and NH 138.
National Highways Authority of India Functions
The National Highways Authority of India Act (NHAI Act) was formed by the Indian Parliament in 1988 after passing the law to establish the NHAI as an autonomous body responsible for the development, maintenance, and management of the country’s National Highways. This legislation grants NHAI the authority to administer the construction, operation, and upkeep of highways, while also regulating traffic on these roads. Key provisions of the NHAI Act include:
- Establishing NHAI as an independent body to manage the National Highways network.
- Granting powers to construct, operate, and maintain National Highways.
- Enabling funding for highway projects through loans, grants, and bonds.
- Creating the National Highways Fund to finance infrastructure development.
- Authorizing NHAI to acquire, manage, and dispose of property, along with entering contracts and agreements.
- Regulating and managing traffic on National Highways.
- Empowering NHAI to impose and collect tolls and fees.
- Setting up a National Highways Tribunal to address disputes related to National Highways.
